The present applicationis a Vdivision of an earlier application filed byme on December 3l, 1917, Serial No. 209,729, which application was acontinuation in jpart of a still earlier application filed by meDecember BO, 1915, Serial No. 69,392, now Patent- No. messen dated Manni2, uns.

The invention has been developed and for convenience will be describedas embodied in a machine for applying so-called double button and stringfasteners to envelopes.

For convenience in the description of the particular embodiment of thisinvention, it may be. noted that such envelopes are generally providedwith a comparatively stiff fastening washer upon the outside of the bodyof the envelope'united thereto preferably bymeans' of an eyelet which isupsetto engage the washer and hold it securely in position in relationto the body ofthe envelope. A similar fastening` washer is similarlyaliixed to the flap of the envelope and preferably ai comparativelylight rein-v forcing washer is used upon the inside of the flap; the twobeing fastened by'an eyelet passed through the washers and through tl. eenvelope flap. The string, which is used to effect the closure of theenvelope,`prefer ablyY has one end fastenedl under the eyelet whichattaches the cooperating` washer Renewed February 9, 1923.

In the following description of the illustrative embodiment of theinvention, the

n general structural features of the machine will first be described andthen, in the se` quence indicated, the illustrative mechanism foraiiixing the fastener and washer to the body of the envelope; theillustrative mechanism for forming and atixing the fastener andreinforcing washer tothe flap of the envelope; and lastly theillustrative mechanism for feeding, fastening and cutting the string.

Referring to the drawings it will be seen that the` greater part of themechanism is mounted upon a bed-plate or table 1 supported uponstandards i?. A main shaft' i3, journal'led in suitable bearings uponthe table 1, is provided with a balance wheel fl and is adapted to beconnected with a driving pulley 5 by a suitable clutch mechanism locatedat the right hand side of the machine. The driving wheel 5 carries a jaw6 and is. during the operation of the machine, rotated continuously froma suitable source of power.

The operation of the machine to aflix the double button and stringfastener.7 is preferably accomplished in one revolution of the mainshaft 3 and the clutch mechanism is therefore designed to rotate themain shaft through one revolution and then automatically disengage. Aclutch collar 7 is keyed to the main shaft (see Figures and 11) and isslidable thereon. This collar has jaws 8 to co-operate with jaws 6 onthe hub of the driving pulley which rotates freely on the main shaft,and a spring pressed plunger 9 tends normally to force the jaws intoengagement. A flange 10 upon the collar '7 has a cam surface 11 and, asshown in Figure 11, this cam surface bears against a stud 12 which holdsthe collar 7 away from jaws 6. The stud 12 is held normally in theposition shown in Figures 2 and 10, by a spring 13 which is attached tothe bed of the machine and to a lever 14 passing through the lower endof the stud. A treadle 15 is connected by suitable links 16 and 17 withthe lever 14 so that upon depression of the pedal and its immediaterelease, the collar 7 will be forced to the right in Figure 10 to engagejaws 6 and 8 and rotate the main shaft 3 through one revolution, thestud 12 co-operating with the cam 11 to withdraw the collar 7 toward theend of the single revolution.

As shown in Figure 3 a notched collar 18 is fast to the main shaft 3 anda spring pressed lever 19 engages the notch in the collar 18 to preventthe back lash of the main shaft.

Coming now to the mechanism for affixing the fastening washer to thebody of the envelope and referring particularly to Figures 3 and 4,means are provided for feed-V ing through a strip of tape, forming awasher from the tape, feeding an eyelet into the proper position andactuating the washer forming mechanisml to affix the washer to the bodyof the envelope. In Figure 3 it will be seen that shoe 2O projects froma stationary part of the machine and carries an anvil 21. A light springguard 22 is fastened to the outer end of the shoe and overlies the anvil21. This spring serves to press the body of the envelope away from theanvil when the fastening eyelet has been upset and contributes to thespeed of operation of the machine by permitting a direct withdrawal ofthe envelope. T he shoe, anvil and releasing spring are shown in sectionin Figure 4. A light spring 256 (see Fig. 3) serves to press theenvelope flap toward the side of the shoe so that it may be quicklywithdrawn from the machine atthe completion of operation. v

Slidably mounted in the machine, as shown in Figure 3, is areciprocating plunger 23. Suitable means are provided for actuating thisplunger from the main shaft, the same being herein shown ascti-operating beveled gears and the latter being mounted upon a shaft 26suitably journalled in the frame, and carrying at its end opposite thegear 25, a crank arm 27 to which a connecting rod 28 is attached. rl`heconnecting rod is attached at its other end to a cross bar 29 which isfastened to the plunger 23 by means of a block 30 and collars 31.Through this connection the plunger 23 will be moved forward and backupon a single revolution of the main shaft. Referring to Figure 4 asecond plunger 32 is mounted below the plunger 23 and carries at its enda punch Suitable means are provided to actuate the plunger 32simultaneously with the plunger' 23, a block 34 connecting the two attheir outer ends. The plunger carries a hollow punch 35 with a slidingpin 36 pressed forward by a spring 37 which is mounted within the punch35. A die plate 38 is rigidly attached to the machine and is providedwith a hole 39 to cooperate with the punch 35 and a hole 4() toco-opera'te with the punch A vertical channel 41 is formed by a guardplate 42 interposed between the die plate and the punches. rThrough thischannel is drawn a strip of tape 43 from a. supply roll 44, shown inFigures 1 and 2 as mounted upon a spindle 45 projecting from one of thestandards of the machine.

Suitable means are provided to draw the tape step by step through thechannel 41, the increments of movement corresponding to the distancebetween the axes of the punches 33 and for a purpose which willhereafter appear. T ape feeding means are herein shown as a pairofco-operating feed rolls 46 and 47, shown diagrammatically in Figure 4,and also in Figures 2 and 3. Suitable means are provided to actuate thefeed rolls, the saine being herein shown as a cam operated ratchet andpawl mechanism. The upper feed roll is mounted upon a shaft 48 suitablyjournalled in bearings which permit it to be pressed toward heco-operating feed roll 47 by set screws 49, This shaft also carriesanother feed roll which will be later referred to. A ratcuet 50 (seeFigure 3) is fast to the shaft 48 and a spring pressed pawl 51 iscarried upon a pivoted arm 52 which is actuated through a link 53 by anarm 54 upon a vertically slidable standard 55 suitably journalled in thebedplate of the machine and held in lowered position by a spring The arm54 carries a roller which rides upon a cam 58 fast to loo 1 (l il aneyelet so that it may be picked up by the f pm 36, Figure 4, in theplunger 35 and carried forward, passed through a holelin the washer andthereafter upset against the an-l vil 2l to fasten the washer to theenvelope body. Such means are herein shown as follows: Referring toFigure l a suitable eyelet selector box is mounted upon a shaft 6ljournalled in suitable bearings above the machine. rihe eyeletbox,yshown in more detail iii Figure l2, may be `of any suitable constructionadapted to delivereyelets to a channeled gutter leading to the eyeletup-. setting mechanism. The boX is rotatedfrom the niain shaft throughbelts 62 and 63 runiiiugover pulleys 64,65, 66 and 67.

The eyelet box deli-vers eyelets to the gutter and the eyelets willslide downthe gutter until they reach-an escapemeiit mechanism, shown inFigures 7` 8 and This cscapenunt mechanismiis adapted to releasetheeyelets one at time `and permitthe released eyelet to fall tothebottoniof the gutter where it is in position for engage-y Referr ringparticularly to Figures 7, 8 and 9 it nient by thek upsettingmechanism.-

will be seen `that the `escapement mechanism comprises areciprocatorymember 71 having two knifeedges 72 andf73 staggered inrelation tothe gutter. As shown'in Figure 7 the eyelets are intended topile upand be` caught upon the upper knife edge 72. Upon a reciprocationof themember 7l to the right, the knife edge72 will release-an eyeletfronrthe coluiniiof eyelets and perinit it to drop, against the knifeedgew73w llpon the reversefreciprocationto the left,

knife edge will pass betufeen-the eyelet-rest vthe feed roll'actuatingarm 54. Thus when the feed roll is actuated to move the strip ing downthe gutter froInthe escapement mechanism is stopped andheld in alignmentwith the pin 36.

The washer thusformedis vcarriedforward vby the punch and pin and posi-` tionedagainstthe envelopevbody.` Finally. the'eyelet will be vforced through theholein the Washer and through the material of the envelope and upsetagainst the anvil 21. At

As soonas the gates 77 have closed behindL the punch35, the eyelet escapeinentmechanism maybe actuated to drop another ,eyeletv into position;thus-completing. a.

single cycle of operationof this `part of theVA apparatus. t

Proceeding withV thedescription of the-- mechanism,` .the means forforming andafti.\l ing areinforcing washer to the flap of the.

.envelope is bestshown in Figure 5 and its 1 relative location to themechanism pist deforivard, the eyelet escapement.mechanism` scribed isbest shown in Figure Refer-l ring to Figure 5, a Lreciprocatingplunge-1&8() is `suitably inountedin the bed Aof the machine and isadapted vto be `actuated in unison with the plunger 23, It is connectedto the44 cross ban 29-by ablock 81 as shownin Figure 3. .l ust belowvthe plunger SO is a plunge er 82 also fastened in the. .block 8l. Theendl of the plunger forms a punchwhich co1.

operates with a hole 83 in a die plate 84 and the plunger carries anupsetting anvil 8,5.. Theplunger ,82 carriesapunch 86 to. co-` operatewith a hole 87 in thedie plate .84. A channel-88, Figure 5, vis formedbetvveenithe supported by the pin 36, which asthe punch s die plate 84and the two punches and through this channel is passed a strip ofreinforcing washer material 89. This strip is drawn from a supply roll89', Figure 1, mounted upon a spindle 89 projecting from one of thestandards 2 and is led up over a guide roll 90 and between feed rolls 91and 92; the feed roll 91 being mounted upon the same shaft 48 whichcarries the feed roll 46 and the feed roll 92 being mounted upon a shaft93 upon which the feed roll 47 is also mounted. The feed roll 91 isrotated with feed roll 46 and the tape 89 is moved forward step by stepas is the tape 43. Thus at each reciprocation of the block 81 the punch86 will form a small hole in the tape andl the punch 85 will cut out aportion of the tape to form a washer and carry it forward for a. purposewhich will appear later.

Aligned with the plunger is a cooperating reciprocating plunger 100slidably mounted in the frame of the machine. J ust beneath the plunger100 is a smaller plunger 101 corresponding to the plunger 82. These twoplungers are actuated from the main shaft 3 through beveled gears 102and 103 best shown in Figure 3. The bevel 103 is mounted upon ashaft 104suitablyT journalled in the frame of the machine and this shaft carriesa crank arm 105 which is connected by a connecting rod 106 with a block107 secured to the plunger 100. The plunger 101 is suitably connectedwith the plunger 100. At each revolution of the main shaft 3 theplungers 100 and 101 are moved forward and back as in the case of theother plungers.

The end of the plunger 100 forms a punch 109 while the end of theplunger 101 carries a punch 110. A die plate 111 is rigidly mounted uponthe machine and is provided with a hole 112 to cooperate with the punch109. 1t is also provided with a smaller hole 113 to cooperate with thepunch 110. Between the die plate 111 and the ends of the plungers is aguide plate 114 which forms a channel 115 through which a strip of tape116 is drawn by suitable feed rolls.

lVithin the punch 109 is a pin or rod 117 which is free to slide thereinand is pressed normally outward by a spring 118. This spring is bestshown in Figure 6 which is a horizontal section through the center lineof the plunger 100. It is desired to have the pin 117 projected from thepunch 109 at the beginning of the cycle of operation of the machine forpurposes which will hereinafter appear. Suitable means are thereforeprovided to release the pin upon the start of operation; the same beingherein shown as a trigger mechanism best illustrated in Figure 6.Attached to a fixed abuemcnt is an arm 119 pivoted at 120 and free torotate only in a clockwise direction on the pivot from the positionshown. Pivoted at 121 within the )lunger is a trigger 122 which has anoutwar ly projecting arm 123 carrying an upstanding pin 124. The plunger100 is shown in its completely retracted position in Figure 6. Uponforward movement of the plunger the pin 124 will contact with a camsurface 125 of a cam plate 126 fastened to the underside of the arm 119.The arm being restrained from movement toward the punch, the triggerwill be drawn away from the enlarged end of the pin 117 and the pin willbe released and shot forward by the spring 118. As the plunger movesforward the pin 124 will move along the cani plate 126 until the arm 123contacts with a spring 127 which tends to hold the arm 119 in theposition shown. At this time the end of the pin 117 will have come incontact with the advancing anvil on the plunger 80 and be held fromfurther forward movement so that the relative movement of the pin 117with respect to the plunger 100 will be toward the right to compress thespring 118. Therefore as the plunger progresses further toward the left,the trigger 122 will bear against the enlarged end of of the pin 117 andfinally snap behind the enlarged end so that the relative position ofthe plunger, pin and trigger will be the same as that shown in Figure 6.At about this time the plunger will be retracted from its advancedposition and the pin 124 on the trigger arm will pass under the arm 119and contact with the cam surface 128 on the cani plate 126. The arm 119will be rotated slightly in a clockwise direct-ion during the retractilemovement of the punch until the parts come substantially into theposition shown in Figure 6 when the arm 119, urged by the spring 127will snap back into the position shown.

Means are provided for drawing the tape 116 through the channel 115 andare substantially similar to corresl'ionding means acting upon the othertapes. The tape roll 130, Figure 1, is supported upon a spindle 131attached to one of the standards of the machine and the tape is drawnfrom this roll through the channel, over a guide roll 132 and betweenfeeding rolls 133 and 134. The feed roll 133 is mounted upon a shaft 135which is joui-nailed in sliding bearings so that the feed rolls may bebrought together by set screws 136.

As in the case of feed rolls 91 and 46, suitable means are provided forintermittently rotating the feed roll 133 to feed the tape step by step.A ratchet 137 is fast to the shaft 135 and a spring pressed pawl 138mounted upon an arm 139 is actuated through a suitable link connection140 from an arm 141 carried by a standard 142. The arm 141 has a roller143 contacting with a cam 144 upon the main shaft 3 and the roller ismaintained in contact with the cam by a spring 145. Eyelet feeding meanssubstantially like that described in connection with the punch`35 areutilized to position an eyelet in front of the punch 109. The eyeletfeed box 150 is driven through belts 151 and 62 the former running overpulleys 152 and 153. A gutter 154 leads from the eyelet boX totlie'hinged gates 155 which position the eyelet at the'axis of thepin117.

An escape'ment mechanism similar to that operating upon the eyelets inthe gutter 70 is provided to operate upon eyelets in the gutter 1.54.shown in Figure 15 and the link connections 157 to an arm 156 upon thearm 141.

The operation of the parts just described may be understood from Figure5. First with respect to the anvil carrying plunger 80. It will beobserved that upon reciprooation this plunger will movetoward the tape89; the anvil pin passing` through a hole in the tape which has beenpunched at the previous operation yby the punch 86. The end of rthe,plunger 80 coming into contact with the tape will punch out a portion ofthe tape to rform a washer rand carry it forward.

Upon the other side. the initial movement of the plunger 100 willoperate to release the pin 117 which will be moved forward,

passed through an eyelet, which is positioned in front of it, throughafhole in the tape 116 which has been punched in the previous operationby thefpuneh 110 and will come in contact with the anvil pin 65 beforethe plunger 110 has travelled `very far. During further forward movementof the plunger 100 the string feedingmeans, which are about to bedescribed, may operate. Upon further movement the punch 109 will openthe gates 155, pass the guide 114 and Contact with the tape 116, cuttingouta portion to form a washer and carrying the eyelet and washer forwardto the ycentral position. The plunger-s 80 and 100 thus form the washersor buttons and position them against opposite sides of the flaporyblanlr, and the actuation of the plungers not only forms the washersandk positions them against the envelope. but also sets the eyelet whichserves as a fastener by which the washers are afiiXe-d to the envelopeflap. The description of the completion of the operation will bereserved until the string feeding means has been described.

The attachment of the stringl to the itiap of the envelope is preferablyeffected by looping the string around the pin 1.17 before An escapementbar 1.56 is `gear in the absence of any control thereof by Y thereaftercaught between the envelope 'Hap and the reinforcing washer and firmlyheld there by the flanges of the eyelet.

Means for accomplishingV this result are herein shown as a hollow gear200 mounted. within a suitable housing and' rotatingconcentricallyaboutthe pin 117 and of suficient size to permit the pun'ch109 to passtherethrough. This gear is rotated from the main shaft 3 by a suitabletrain of gearing comprising the gears 201, 202'and 203 and is preferablyrotated at a greater speed than the main shaft. 1n this instance thegear 200 which, with its associated parts` rwill hereinafter be termedthe looper makes four revolutions to one revolution of the main shaft.Means are provided on the gear to grasp the end of a string which ispresented to the loop'er by means hereinafter described, the stringgraspingmeans being herein shown as a substantially U-shaped member 204,Figure 20, normally spring pressed against the face of the gear butadapted tov be extended from the face of the gear at the proper momentin the operation of the machine when it is desired to grasp a piece ofstringpresented thereto.` This U- shaped member 204 extends through thegear and is fixed to a ring 205 having cam surface 206. The constructionof this looper will be more readily seen from Figures 19, 20 and 21which are respectively an end view, front view and cross-section of thelooper. The ring 205 is normally held away from the gear by springs 207and its movement is limit-ed bythe string engaging member 204. Thus, itwill he seen that when an end of a string is placed under the member204, it will be firmly grasped "between this member 204 and the face ofthe the ring 205 with its cam surface 206.

Means may be provided to control the opening and closing of the member204 for the purpose of threading the string thereunder, the said meansbeing herein sho-wn as a cam'208 mounted upon a lever 200 andkcont-rolled by a cam 210 upon the main shaft (see Figure 15). As thisparticular mechanism is designed to operate, it is desirable to have thelooper opened for grasping the string once in its fourrevolutions,rth'at is.' at a time when the pin 11T yis extended. 1t willtherefore be seenthat when the cam 208 is brought to the position .shownin Figure 15, the looper, rotating in a counterclockwise direction'willbe opened by the cam 208 for threading the string. As the loopercontinues to rotate the high point ot the cam surface 206 is rotatedpast the cam 208 and the string engaging member' 204 will grasp thestring end which has been presented to it and will wind the string aboutthe pin 117 until the string is released or withdrawn 'from the looper.

Means may be provided to present the end of a string to the loopermechanism so that it mav be engaged by the member 204 and the rim ot thegear 200, the same being herein shown as a reciprocating string carry#ing member 215 and its associated parts. This string carrying member isprovided with a linger 216 having a resilient side plate 21'( to engagethe string when it is threaded therethrough and to tension the stringduring the succeeding operations. The string carrying member 215 ismounted in a guideway 21S and is reciprocated by a crank arm 219 andlink 220. the crank arm being mounted upon a shat't 221 which in thisparticular instance, is driven in synchronism with the main shaft 3through a train of gears 222,

Means may be provided to sever the string, the same being herein shownas shears 230 having a lined blade 231 and movable blade 232 and mountedupon an oscillating member 233 pivoted at 234 upon the guideway. The twoblades oit' the shears are -pivoted at 235 and are held in operativerelation by anyr suitable means herein shown as a stud and spring 236.Suitable means may be provided to bring the shears intoY position torcutting the string, the same being herein shown as a cam 23T upon theoscillating shears mounting adapted to be engaged by an anti-Frictionroller 233 upon the string carrying member 215 to oscillate the shearsand bring them into operative position tor cutting the string. Theshears mounting is shown in its normal position in Figures 15 and 17 andis yieldingly held in this position bv a spring 239 attached to theshears mounting and to an arm 240 which in turn is rigidly attached tothe guideway 218.

Means may be provided to operate the shears to cause them to ont thestring upon their being brought forward through the aperture 241 in theguideway, such means being herein shown as an anti-'friction roller 242upon the rearwardly extending movable blade 232 of the shears. (SeeFigures 1'? and 1S). This roller 242 vis adapted to be engaged by a pairot cams 243 and 244 which cause the shears to close and openrespectively. l t will be observed that when the shears mounting isoscillated upon the pivot 234 the shears will be swung` forward untilthe anti-friction roller 242 contacts with the cam 243. Upon furtherVtoi-wind nlovement of the shears the cam 243 will 223, 9.2i-, asa andQ27;

operate to bring the cutting edges ot the shears together and thereuponthe machine being so organized as to bring the string between thesecutting edges, the string will be severed just above the threader. Asthe string carrying member is moved upward by the crank and linkconnection with the. shaft 221 the roller 233 upon the string carryingmember will be released from engagement with the cam 237 upon the shearsmounting and allow the same to resume its normal position under theaction of the spring 239. The rearward movement of the shears will bringthe shears operating roller 242 in contact with the cam 244 which willcause the shears to be opened in readiness for the next forward movementpreceding the cutting of the next length of string.

To assist in properly locating the envelope an adjustable table 250, asshown best in Figures l and 2, is positioned in front ot the machine andsupported in a bracket 251. rllhis table may be raised or lowered bymeans of a screw 252 which can be rotated by a handle 253. The screw isthreaded in a bracket 254. The table may be adjusted to a properhorizontal plane b v another screw 255 shown in Figure 2.

The operation ot the machine as a whole may be summarized as follows:Starting with the several parts of the apparatus in thc positions shownin Figures 1. 27 4 and 5, and referring particularly to those ligures`an envelope to which the string closure is to be Vatlixed may beinserted in the machine b'v extending the Hap into the space between thedie plate S4 and the looper 200; the shoe 2O being inserted in theenvelope that the bod;v ot the envelope comes between the shoe 2() andthe die plate 30. The table 2:10 will of course be previouslY adjustedlo position the envelope properly. The envolope being in place thetreadle 15 ma)v be depressed to release the clutch mechanism and startthe rotation of the main shatt 3. The several plungers will start theirtorward movement at a relative speed depending upon the distance. whichthey have to travel. The initial movement et' trie plunger will releasethe pin 11T and shoot it forward into contact with the envelope tlap.The initial rotation of the string looper will cause it to grasp thestring and wind the string about the pin while. the several plungers arecoming forward. Vhen the main shaft has made substantially one quarterrevolution the several punches will have reached their respective tapesand cut out washers therefrom. Yin the case of the plunger 100 the punchwill carry *forward an elvelet and washer upon the pin 11'?. while theplunger 8O cuts out and carries 'forward a reinforcing washer on theanvil pin 83, and the punch 35 cuts out and carries t'orward a washerand eyelet upon the pin When you Cil

the main shaft has completed about the Vfirst half of its revolution,the punch 35 will have a Washer and eyelet `in Contact `With the body ofthe envelope. the anvil'85 Will hold the reinforcing` Washer `incontactwith the iiiside of the flap of the envelope and the punch 109 will holda fastening Washer and eyelet in Contact 4with the outside of the flapofthe envelope, while the string will be Wound upon the pin 11T and whenthe eyelet on the pin has advanced `far enough the string will ride upupon the shank ofthe eyelet.

During this time the string carrier 215 will have descended in itsguide-Wjay until-the roller 238 is nearly in contact With the cam 235 ofthe shears mechanism. At the completion of the first half revolution thepunch 35 Will force the e-yelet carried by it through the paper of thebody 0f the envelope and upset itl against the anvil thus securing thefastening washer to the body of the envelope, ivhile the cooperatingplungers 8O and 100 will force an eyelet through the fasteningandreinforcing,Washers andthe fiap of lthe envelope and upset it to securethe Washers and stringfirmlythereto. At substantially this time theshears ivillbe moved forward to cut the string at the proper point.

During thesecond half revolution ofthe main shaft the several plungersivill be retracted to their starting positions, the tapes advanced onestep and an eyelctdropped to the bottom ofveach gutter, and the stringivcarrier will'have returned to the position of Figure 5 to place an endof the string Where it can be graspedby the looper. This conr pletes asingle cycle operation and places the machine in position for its neXtoper-k be variously modified and embodied Within the scope of thesub-joined claims.
